As coarse crushing equipment, jaw crusher is indispensable crushing equipment in mining crushing equipment. It is mainly used for coarse crushing in the ore crushing process and for the first crushing of sand and gravel production lines. They are relatively large, and can be fed below 1300mm, and the output generally ranges from a few centimeters to tens of centimeters, which can be adjusted according to their own needs. Jaw crusher has the characteristics of large crushing ratio, uniform product granularity, simple structure, reliable work, easy maintenance, and economic operation costs. Among the many crusher products, jaw crusher is currently widely used and effective equipment. It is mainly used for medium-size crushing of various ore and large materials. It can crush materials with compressive strength not greater than 320Mpa. 

What are the performance advantages of a jaw crusher?

The discharge range of the jaw crusher has a large adjustment range, which increases the flexibility of the crusher and can meet the user's various processing needs. In addition, the bearing part of the jaw crusher adopts an integral cast steel structure. The integral cast steel bearing seat can ensure complete cooperation with the crushing frame, and also greatly enhances the radial strength of the bearing seat. There is no dead zone in the cavity crushing, and the material will not be blocked in the crushing cavity, which improves the production efficiency. The working mode of the jaw crusher is a curved extrusion type. Its working principle is: the motor drives the belt and the pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw of the crusher rises, the angle between the toggle plate and the movable jaw it becomes larger, so that the movable jaw plate is pushed closer to the fixed jaw plate, and at the same time, the material is crushed or split to achieve the purpose of crushing. When the crushing motorized jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the tie rod and the spring. At this time, the crushed material is discharged from the lower mouth of the crushing chamber. With the continuous rotation of the motor, the motorized jaw is crushed for periodic movement to crush and discharge materials, achieving mass production.

What fields can jaw crushers be applied to?

1. Mining industry. Since the raw ore materials are relatively large, a certain crushing treatment is required during mining, which is convenient for transportation. The jaw crusher has a large crushing ratio and a uniform product size. The discharge opening has a large adjustment range, which can meet the requirements of different users and other superior performance. It is ideal crushing equipment for various mining resources.

2. Construction industry. For the construction industry, the various concretes used need to be crushed to meet the required granularity before they can be applied to construction production; such as the application of raw material crushing processing in cement production, the application in concrete production, and even construction The application of waste recycling, etc. In short, the development of the construction industry cannot be helped by the jaw crusher.

3. Road construction. The road construction industry is the same as the construction industry. The materials required for road construction must be crushed, and the relatively high efficiency of jaw crushers is exactly what is needed in road construction.

4. Water conservancy industry. In recent years, the demand for sand and gravel aggregates for water conservancy projects is very large. Its ancillary projects in the early stages include the construction of production and living infrastructure and the construction of construction roads, as well as the main construction of pivotal projects in the later stages, which require a large amount of aggregates. The supply and production of these large quantities of sand and gravel aggregates are also inseparable from the participation of jaw crushers.
